Pete Sampras won 14 Grand Slam titles using the ProStaff 6.0 Original. Available in 85 or 95 square-inch head sizes, the 85 still enjoys almost cult status among 5.0+ level players and also racquet collectors. According to tennis-warehouse.com, "this is likely due, in no small part, to some of the famous players who have used this racquet. There's no doubt that the 6.0 is not for everyone. However, for the purist player, who possesses solid strokes and is accustomed to a hefty, head light balance, the ProStaff 6.0 is as good as it gets." The Wilson ProStaff of course actually was not developed for Pete Sampras, who back then still was a child. It was developed with the intention to construct new carbon racquets for two of America`s outstanding tennis player legends who still used to play old-fashioned wood racquets back then: Jimmy Connors and Chris Evert. They both started playing the ProStaff in 1984. Until then, throughout his whole career, Connors had played the Wilson T2000, it seemed to be his elongated left arm. Connors was closely involved in the conception process of the ProStaff. Chris Evert had previously played the Wilson Chris Evert Autograph. 1985, however, saw Connors again playing his old T2000! It was not before 1987 that he definitely turned to playing a carbon racquet, when he contracted with Slazenger. Chris Evert, in contrast, played the ProStaff until the very end of her career in 1989.
